Primary flight controls govern the aircraft’s roll and pitch by moving the ailerons, elevators, rudder and spoiler. Our fixed-wing primary flight control actuation and trimmable horizontal stabilizer actuator (THSA) solutions provide commercial and military platforms with significant benefits:

  • Greater reliability
  • Lower operating and maintenance costs
  • Improved product performance
  • A redundancy of moving parts, allowing for weight savings

Primaries – fixed wing

Collins Aerospace draws on more than 50 years of experience in the actuation industry to offer you a wide array of primary flight control actuation, both mechanical and electronic. Our solutions include technologies for fly-by-wire, electro-hydrostatic, electrical back-up hydraulic actuator and electric actuators.

We also offer customized test vertical system integration and iron bird capabilities.

Electro-Mechanical Actuator (EMA)

Our extensive experience for actuation systems capabilities for fly-by-wire has resulted in more than 10 billion flight hours. Fly-by-wire solutions are controlled by servo-valves or direct-drive valves. They use the most advanced technology for primary flight control actuators on a variety of large commercial, regional, business and military fixed-wing platforms.

Trimmable horizontal stabilizer actuator (THSA/HSTA)

When your civil or military platform requires THSA – a ball screw driven and operated electronically or hydraulically – consider what Collins Aerospace can offer. Our experience, combined with customization and full-integration capabilities, can provide a cost-effective, complete solution for your THSA/HSTA needs.

Our THSA/HSTA solutions are certifiable to the latest airworthiness requirements. We also are equipped to provide hydraulic fly-by-wire or electromechanical actuator solutions for optimized aircraft system architecture.

See the Collins Aerospace difference for fixed-wing primary and THSA solutions – and why aircraft manufacturers rely on us for world-class support and guidance in making an optimal choice for their aircraft.
